<h1>UTF-8</h1>

<h2>Erlang</h2>
	
The main thing you should know about Erlang unicode is that
<code>
1> unicode:characters_to_binary("UniText") == <<"UniText"/utf8>>.
</code>
I.e. in N2O DSL you should use:
<code>
2> io:format("~tp",[ #button{body= <<"Unicode Name"/utf8>>} ]).
</code>

<h2>JavaScript</h2>
Whenever you want to send to server the value from DOM element you should use utf8_toByteArray.

<code>    
> utf_toByteArray(document.getElementById('phone').value);
</code>
<p>However we created shortcut for that purposes which knows about radio, fieldset and other types of DOM nodes. So you should use just:</p>
<code>
> querySource('phone');
</code>
<p>querySource JavaScript function ships in nitrogen.js which is part of N2O JavaScript library.
Whenever you get unicode data from server you should prepare it before place in DOM with utf8_decode:</p>
<code>    
> console.log(utf8_decode(receivedMessage));
</code>
